so you're going to need to find the slope. in order to do that use (y2-y1)/(x2-x1)

(7-(-2))/(0-8)

simplify

9/-8

simplify -9/8

now using y=mx+b, we need to find b. so we can plug in the coordinates of (0,7) or (8,-2). let's use (8,-2) because it involves more math.

y=mx+b

-2=(-9/8)(8)+b

multiply (-9/8) by 8 to get -9

-2=-9+b

add 9 to both sides

7=b

so our equation is now

y=-(9/8)x+7

Step-by-step explanation:

We can start by setting up what we know of the slope-intercept equation, which is the slope.

[tex]y=\frac{5}{4}x+b[/tex]

Now, we can use the given point to find the y-intercept.

(-4,22)

Step-by-step explanation:

Answer:

(- 4, 22 )

Step-by-step explanation:

To determine which point lies on the graph, substitute the x- coordinate of the point into the equation and if the value obtained is equal to the y- coordinate of the point then it lies on the graph.

(1, - 2 )

y = - 4(1) + 6 = - 4 + 6 = 2 ≠ - 2 ← not on graph

(- 4, - 10 )

y = - 4(- 4) + 6 = 16 + 6 = 22 ≠ - 10 ← not on graph

(- 4, 22 )

y = - 4(- 4) + 6 = 16 + 6 = 22 ← lies on graph

(1, - 10 )

y = - 4(1) + 6 = - 4 + 6 = 2 ≠ - 10 ← not on graph

You are making a new type of deodorant from two different mixtures the first mixture is 30% smell proof and the second mixture is 80% smell proof to make a safe make sure it needs to be 50% smell proof how much of each makes you need if you want 1000 L total

Answers

Answer:

600 L of 30% proof and 400 L of 80% proof is needed

Step-by-step explanation:

Let the amount of 30% smell proof be x while that of 80% smell proof is y

Then;

x + y = 1000 •••••(i)

Also;

30% of x + 80% of y = 50% of 1000

0.3x + 0.8y = 500 •••••(ii)

From i, x = 1000 - y

Put this into ii

0.3(1000-y) + 0.8y = 500

300 - 0.3y + 0.8y = 500

0.5y = 500-300

0.5y = 200

y = 200/0.5

y = 400 L

But x = 1000 - y

x = 1000 - 400 = 600 L

  3.  m∠A < 80°

Step-by-step explanation:

The exterior angle NGS, marked as 80°, has a measure that is the sum of the measures of the remote interior angles: GAN, GNA.

If we assume that angle measures cannot be zero, then we must have ...

  m∠A +m∠N = 80°

  m∠A = 80° -m∠N

Since m∠N > 0, the measure of angle A must be less than 80°.

Step-by-step explanation:

Given

[tex]Cubes = 2[/tex]

[tex]Sides = 4cm[/tex]

Required

Determine an expression for its volume

Find the volume

Volume of a cube is:

[tex]Volume = x^3[/tex]

Where x represents the length of a side

So, volume of 2 cubes would be:

[tex]V= x^3 + x^3[/tex]

[tex]V= 2x^3[/tex]

Solving (b): Volume when x = 4

Substitute 3 for x in [tex]V= 2x^3[/tex]

[tex]V = 2 * 64[/tex]

[tex]V = 128[/tex]

What is Linear equation in one variable?

The linear equation in one variable is an equation which is represent in the form of ax + b = c, where a and b are two integers and x is a variable and has only one solution.

Here, Plan A costs $5 per month plus $2.50 per movie watched.

A = 5 + 2.50 x

here, x is movies per month.

And Plan B costs $24 per month  plus $1.50 per movie watched.

B = 24 + 1.50 x

When Lydia plans on watching 21 movies each month.

x = 21

⇒ A = 5 + 2.50 (21) = 57.50

⇒ B = 24 + 1.50 (21) = 55.50

So, Lydia Plan B would be 2 dollars cheaper than plan A.

Manny is buying new clothes for school. He buys three shirts for $14.95 each and a tie for $12. Everything in the store is on sale for 15% off. What is Manny's total cost?

Answers

Given:

Cost of each shirt = $14.95

Cost of a tie = $12

Discount on Sale = 15% off

Manny buys three shirts and a tie.

To find:

The Manny's total cost.

Solution:

We have,

Cost of 1 shirt = $14.95

Cost of 3 shirt = 3 × $14.95

                       = $44.85

Cost of a tie = $12

Total cost before discount = Cost of 3 shirt + Cost of a tie

                                            = $44.85 + $12

                                            = $56.85

Everything in the store is on sale for 15% off. So,

[tex]\text{Manny's total cost}=56.85-\dfrac{15}{100}\times 56.85[/tex]

[tex]\text{Manny's total cost}=56.85-0.15\times 56.85[/tex]

[tex]\text{Manny's total cost}=56.85-8.5275[/tex]

[tex]\text{Manny's total cost}=48.3225[/tex]

Therefore, the Manny's total cost is $48.3225.
